General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible chemi-
cals and fluids, or using worn or damaged parts, can cause
them to rupture and result in fluid injection, splashing in the
eyes or on the skin, or other serious bodily injury, or fire, ex-
plosion or property damage.
NEVER alter or modify any part of this equipment; doing so
could cause it to malfunction.
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately.
Toxic fluids may be used with this heater. Consult the fluid
and solvent manufacturer to understand and protect against
associated hazards. Always wear protective eyewear, gloves,
clothing and respirator as recommended by that manufac-
turer.
Do not expose the heater to rain.
Do not operate the heater with any covers removed.
Do not use the heater with flammable liquids, such as those
having flash points below 200 F (93 C).
Static electricity is created by the flow of fluid through the
pump and hose. If every part of the spray equipment is not
properly grounded, sparking may occur, and the system may
become hazardous. Sparking may also occur when plugging
in or unplugging a power supply cord or using a gasoline en-
gine. Sparks can ignite fumes from solvents and the fluid be-
ing sprayed, dust particles and other flammable substances,
whether you are spraying indoors or outdoors, and can cause
a fire or explosion and serious bodily injury and property
damage.
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING IMMEDI-
ATELY. Check the entire system for positive grounding. Do
not use the system again until the problem has been identi-
fied and corrected.
Grounding
To reduce the risk of static sparking, ground the spray system
and all other spray equipment used or located in the spray
area. CHECK your local electrical code for detailed grounding
instructions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1. Pump: connect a ground wire and clamp (supplied) to a
true earth ground as shown in your separate pump
manual.
2. Fluid hoses: use only grounded hoses with a maximum
of 500 ft (150 m) combined hose length to ensure
grounding continuity.
Moving parts can pinch or amputate your fingers or other
body parts. KEEP CLEAR of moving parts when starting or
operating the spray system. Follow the Pressure Relief Pro-
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards
– particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.

IMPORTANT
System Pressure
This heater has a 3000 psi (210 bar) MAXIMUM WORKING
PRESSURE. Be sure that all spray equipment and accesso-
ries used are rated to withstand this pressure. DO NOT ex-
ceed the maximum working pressure of any component or
accessory used in the system.
Be sure all accessories added to the system are properly
rated to withstand the maximum air and fluid working pres-
sures of this system.
NEVER install any fluid shutoff device at the fluid outlet of
either heater or filter. Shutting off the fluid at the outlet causes
high back pressure which can cause component rupture and
result in serious bodily injury.
Fluid and Solvent Compatibility
Be sure that all chemicals used in the spray system are
chemically compatible with the wetted parts shown in the
TECHNICAL DATA on page 40. Consult your chemical
supplier to ensure compatibility.
3. Air hoses: use only Graco heated hose, which are elec-
trically grounded.
4. Heater: by wiring to a positively grounded power supply.
In a mobile installation, be sure the truck or trailer is
grounded to a true earth ground.
To ensure positive grounding and further reduce the risk
of electric shock, redundant grounding is recommended.
The long lines of the shielded-wire heated hose have
higher than normal capacitive leakage current to ground.
5. Spray gun: obtain grounding through connection to a
properly grounded fluid hose and pump.
Object being sprayed: according to local code.
6.
7. Fluid supply container: according to local code.
8. All solvent pails used when flushing, according to local
code. Use only metal pails, which are conductive. Do not
place the pail on a non-conductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
9. T o maintain grounding continuity when flushing or reliev -
ing pressure , always hold a metal part of the gun firmly to
the side of a grounded metal pail, then trigger the gun.
Electrical Wiring
All electrical wiring should be performed only by trained and
qualified personnel in compliance with all local codes and
regulations.
Flushing Safety
Reduce the risk of fluid injection injury, static sparking, or
splashing by following the flushing procedure given on page
12. Follow the Pressure Relief Procedure on page 4, and
remove the nozzle before flushing. Hold a metal part of the
gun firmly to the side of a grounded metal pail and use the
lowest possible fluid pressure during flushing.
cedure on page 4 before checking or servicing any part of
the spray system, to prevent it from starting accidentally.
